The trim board 21 is provided with a speaker grille 22, a door pocket 24, an inside handle mounting portion 25, an opening 28 for mounting an armrest, and the like.

  The clip seat 30 is provided on the outer surface of the trim board 21 and a plurality of clip seats 30 are provided along the peripheral edge of the trim board 21 (see the broken line in FIG. 1). The trim board 21 and the clip seat 30 are integrally formed by injection molding a synthetic resin such as polypropylene. A clip 60 is attached to the clip seat 30 as shown in FIG. The clip 60 connects the trim board 21 (first member) and the vehicle door inner panel 10 (second member).

  Next, the attachment structure of the clip 60 to the clip seat 30 will be described. As shown in FIGS. 2 and 4, the clip seat 30 includes a standing wall portion 31 that rises from the trim board 21 toward the door inner panel 10, and a seat surface portion 40 that is provided at the tip of the standing wall portion 31 and to which the clip 60 is fixed. And an elastic locking piece 50 provided on the standing wall portion 31 and disposed on the trim board 21 side with respect to the seat surface portion 40.

  As shown in FIG. 2, the trim board 21 includes a main wall portion 27 constituting a design surface (surface on the vehicle interior side) of the trim board 21, and a vehicle compartment outer side (door inner) from the peripheral end of the main wall portion 27. 2, and in this embodiment, a part of the standing wall portion 31 of the clip seat 30 is formed on the side wall portion 26 of the trim board 21, as shown in FIG. 2. Consists of part. In addition, the standing wall part 31 of the clip seat 30 may be configured by a member different from the side wall part 26.

  As shown in FIG. 2, the clip seat 30 has a box shape (an arrow shape) opened along the surface direction of the main wall portion 27 of the trim board 21. Specifically, the seat surface portion 40 is disposed to be opposed to the main wall portion 27 in the vehicle width direction, and the standing wall portion 31 is U-shaped opened in the opening direction of the clip seat 30 in plan view. It has a shape. The seat surface portion 40 is formed with a clip insertion hole 40A penetrating in the plate thickness direction. The clip insertion hole 40 </ b> A has an opening 40 </ b> B that is opened along the surface direction of the seat surface portion 40. Further, the opening 40 </ b> B is opened in a direction that coincides with the opening direction of the clip seat 30.

  As shown in FIG. 4, the clip 60 includes a shaft portion 61 inserted into the clip insertion hole 40 </ b> A, an insertion portion 64 inserted into the mounting hole 11 formed in the door inner panel 10, and a cover in the shaft portion 61. The locking part 66 provided in the edge part on the opposite side to the insertion part 64, and the locking part 67 provided in the edge part by the side of the insertion part 64 in the axial part 61 are provided.

  The inserted portion 64 is configured to be elastically deformable, and can be inserted into the mounting hole 11 of the door inner panel 10 while being reduced in diameter. As a result, the inserted portion 64 inserted into the mounting hole 11 is elastically restored to be locked to the opening edge of the mounting hole 11 from the outside of the passenger compartment. The clip 60 includes a closing piece 68 that closes the gap between the attachment hole 11 and the insertion portion 64. The locking portion 66 is configured to be locked from the trim board 21 side with respect to the hole edge portion of the clip insertion hole 40 </ b> A in the seat surface portion 40. The locking portion 67 is configured to be locked from the door inner panel 10 side with respect to the hole edge portion of the clip insertion hole 40 </ b> A in the seat surface portion 40. Note that the locking portion 66, the locking portion 67, and the closing piece 68 have an annular shape in plan view.

  As shown in FIG. 4, the elastic locking piece 50 has a locking piece main body 51 that has a cantilever shape extending from the rear wall portion 26 </ b> A of the standing wall portion 31 (a part of the side wall portion 26) to the opening side of the clip seat 30. And a protrusion 52 formed at a location overlapping the clip insertion hole 40A in the locking piece main body 51. The protrusion 52 has a shape protruding from the locking piece main body 51 toward the door inner panel 10, and is fitted in a recess 62 formed on the bottom surface of the shaft portion 61 of the clip 60.

  The protrusion 52 has a substantially hemispherical shape, and has a circular shape in plan view as shown in FIG. The diameter R1 of the protrusion 52 is set to a value smaller than the opening width R2 of the clip insertion hole 40A. And clip insertion hole 40A and projection part 52 are arranged in the form where the central axes correspond. The elastic locking piece 50 is exposed to the door inner panel 10 side through the clip insertion hole 40A.

  Next, the operation of this embodiment will be described. When the operator attaches the clip 60 to the clip insertion hole 40A, the shaft portion 61 is inserted into the clip insertion hole 40A through the opening 40B of the clip insertion hole 40A as shown in FIG. In this process, the protruding portion 52 is pressed against the locking portion 67 of the clip 60, so that the elastic locking piece 50 is elastically bent and deformed with the base end portion as a fulcrum, and the protruding portion 52 extends from the seat surface portion 40. Displaces away. Then, when the shaft portion 61 is disposed in the clip insertion hole 40 </ b> A, the elastic locking piece 50 is elastically restored, so that the protruding portion 52 is fitted into the concave portion 62 of the clip 60. Thereby, the clip 60 is positioned in the surface direction of the seat surface portion 40.

  Next, the effect of this embodiment will be described. According to the present embodiment, the protruding portion 52 of the elastic locking piece 50 is fitted into the recess 62 formed in the shaft portion 61, thereby suppressing the situation where the shaft portion 61 is pulled out from the clip insertion hole 40 </ b> A. Can do.

  The elastic locking piece 50 is exposed to the door inner panel 10 side through the clip insertion hole 40A. With such a configuration, when the clip seat 30 is molded using a molding die, the surface on the door inner panel 10 side of the seat surface portion 40 and the surface on the door inner panel 10 side of the elastic locking piece 50 (FIG. 3). ) Can be formed with a single mold, and the mold can be configured more simply.
